South Arne is an integrated installation operated by Hess Denmark ApS
The South Arne platform comprises a combined wellhead, processing and accommodation platform with an oil storage tank on the seabed and buoy loading facilities for oil.
The processing facilities consist of a plant that separates the hydrocarbons produced as well as facilities for processing the oil, gas and water produced.
The platform also houses equipment for water injection. In order to prevent the depositing of sparingly soluble salts in and around the injection wells, the seawater injected into the field is pre-processed. Thus, the sulphate ions are removed from the seawater prior to injection. The bulk of the produced water is injected into the reservoir.
The oil produced is conveyed to an 87,000 m3 storage tank on the seabed. When the tank is full, the oil is transferred to a tanker by means of buoy loading facilities. The gas produced is transported through a gas pipeline to Nybro on the west coast of Jutland.
The South Arne Field has accommodation facilities for 57 persons.
